You can change this up as you go, make it vegetarian or not
2Cups shortening (brand names might be a little higher quality)
2Tablespoons of cooking oil (grape seed works well)
1 filter material (cheesecloth, fine mesh coffee filter, the fats will clog paper filters)
2.5oz+ of the high quality bud or sugar leaf. (Extracts can be used, just adjust the ratios as needed)
1 5quart sauce pan (also a crockpot)
2 transparent half gallon pitchers (or other food safe vessels)
In the five quart sauce pan mix water, oil, Shortening, and bud shake material (The finer ground the better)
Bring this mixture to boil on high watching closely, when it starts to boil immediately turn down heat to a very low simmer and cover for 18-24 hours. (This is where a crockpot comes in handy)
Turn off heat and let it cool for about 3-4 hours, now use the chosen filter to strain the liquid out of the pan and into the pitchers, make sure too squeeze out as much of the liquids as possible.
Place vessels in the fridge for a couple hours so the canna-shortening will separate and solidify on the top of the water, you can use a knife and run it around the inside so that the canna-shortening is easy to grab and put the oil in a container of your choice.
This works in any recipe that calls for shortening. You can also freeze for long term storage. It should keep for a few weeks in the fridge in a covered container.
